Jamshedpur, Aug. 22: An upper air cyclonic circulation coupled with the shifting of the monsoon trough towards the south will result in rainfall activity over Jharkhand in the next 48 hours.

ďThe upper air cyclonic circulation existing up to 2km is stretched between Sikkim and coastal Odisha. This coupled with the axis of monsoon trough, which shifted to Bihar today from the foothills of Himalayas, will result in showers in the state,Ē said B.K.
